use this in the total row.
First i am converting number to string data type to exract hour and mintues in seprate.After that i have converted mintues to hour and added.
=Sum(ToNumber(Substr(FormatNumber([TIME];"0.00");1;Pos(FormatNumber([TIME];"0.00");".")-1))+ToNumber(Right(FormatNumber([TIME];"0.00");2);"00")/60)
Based on the screenshot total of all entries is 6.2.How are you expecting it should be 7?
time column is based on variable or direct object? in case of variable then use foreach () in sum row and add dimensions which needs to be there.
